When the baler is in use the tank 3l] is utilized for the storage of the liquid preservative. The hose 2l leads from the said tank to the continuous operating pump. The pump may be a conventional gear pump, for example. `Since there is a tendency for forage preservative chemicals to be somewhat corrosive, it is preferred that the members of the pump be made of bronze or other non-corrosive materials. The liquid is carried through the hose 2l and through the nexible tubing l5, and through the nozzle 3i, and is sprayed on the forage. To assure even distribution of the preservative on all parts of the baling forage the nozzle is systematically swung to and fro and this motion of the nozzle is motivated by the upward and downward movement of the tamping bar, and with the simultaneous movement of the T-trigger. As has already been pointed out, the spring bar i8 remains stationary during the operation. At each upward movement of the tamping bar the T-trigger engages the nger l2 and swings it upwardly on its hinge Il until the roller i3 rolls into the radial bend 33. The fingers i2 and l2a remain in the most upwardly position until the tamping bar starts its downward movement. As the downward movement of the tamping bar proceeds the T-trigger engages the linger I2a and the linger 12a and the finger assembly is swung downwardly through the neutral position and further downwardly until the roller rolls into the radial bend 3d. The finger assembly remains in the lowermost position until the tamping bar starts its upward movement. As the tamping bar proceeds upwardly, the T-trigger engages the nger l2 and the swinging movement is repeated. Since the nozzle 3l is secured to the finger assembly member i6 by the radial bar le, the swinging movement of the nger assembly motivates the swinging movement of the nozzle 3 I.

I wish particularly to point out that in co bination with a conventional hay baler, and particularly in combination with a conventional tamping bar of a hay baler, the preservative spraying device of my invention operates automatically without attention of the operator. It is only necessary that the operator maintain fluid in the supply tank. The swinging movement of the nozzle assures even distribution of the fluid over the surface or" the forage as it is fed into the baling compartment 2l or hopper of the baler,

I wish further to point out that the structure of the device of my invention is simple, inexpensive to construct, and by virtue of this novel structure the device is sturdy and requires only a minimum amount of maintenance.

I wish further to point out that the device of my invention has been in operation for a considerable period of time on commercial balers of several different makes and has performed without fail and with excellent results.

Having clearly set forth the construction, utility and advantages of my invention I wish particularly to state that it will be apparent that changes in the details of the construction and arrangement of the various members of the inl vention may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.

I claim:

l. In combination with a forage baler having a tarnping bar, a fluid spraying device comprising a nozzle, a flexible tube, an angle iron bracket, a radial bar, a hinged finger assembly, the said finger assembly comprising a pair of diverging fingers, a roller, a hinge, and an elongated plate, the said fingers being secured by their ends to the extending end of the said elongated plate, said plate being secured to one leaf of said hinge, and the other leaf of said hinge being secured to the said angle iron bracket, the said angle iron bracket being firmly secured to a member of the baler, the said radial bar being disposed between and secured to the said nozzle and the said plate, a spring bar, the said spring bar being secured to the said bracket, the said spring bar comprising integrally a coil spring, a straight bar, a radial portion, and a pair of radial vbends formed in the said radial portion thereof,

the said roller being rotatably secured in an elongated hole in the said elongated plate, the said roller being contiguous with the said spring bar and moves on one surface of the said spring bar, a T-trigger, the said trigger being secured to and disposed on the tamping bar substantially in the position ofthe finger assembly at its neutral position, the upward and downward reciprccating movement of the said trigger with the tamping bar being disposed to engage with one of the said fingers to provide an upward and downward swinging movement of the said nger assembly, the radial movement of the said radial bar, and the swinging motion of the said nozzle.

2. In a device for the application of preservatives to forage, a nozzle, a flexible tube, an angle iron bracket, a radial bar, a hinged finger assembly, the said finger assembly comprising a pair of diverging ngers, a roller, a hinge, and an elongated plate, the said fingers being secured by their ends to the extending end of the said elongated plate, said plate being secured to one leaf of said hinge, and the other leaf of said hinge being secured to the said angle iron bracket, the said radial bar being disposed between and secured to the said nozzle and the said plate, a spring bar, the said spring bar being secured to the said bracket, the said spring bar comprising integrally a coil spring, a straight bar, a radial portion, and a pair of radial bends formed in the said radial portion thereof, the said roller being rotatably secured in an elongated hole in the said elongated plate, the said roller being contiguous with the said spring bar and moves on one surface of the said spring bar, a T-trigger, the said trigger being disposed on a reciprocating means, the upward and downward reciprocating movement of the said trigger being disposed to engage with one of the said fingers to provide an upward and downward swinging movement or" the said finger assembly, the radial movement of the said radial bar, and the swinging motion of the said nozzle.
